1 INTRODUCTION
The DMP Flex 350 production printer is a high quality direct metal printing
(DMP) machine. It brings reliability and repeatability to production-level
direct metal printing. The DMP Flex 350 is designed to meet industrial market
demands of reliable and low maintenance 3D printing machines.
With direct metal printing, parts are built up layer by layer. Using this
technique, complex parts can be made. Loose metal powder particles are
melted together by a high-precision laser. The laser is focused on the powder
particles in order to selectively build up thin subsequent horizontal layers.
By connecting each new layer to the previous one, it brings a high quality
alternative to the traditional manufacturing processes. Since no tools are
used and no material is removed, waste is reduced significantly. Parts are
not built by removing material in subsequent steps, but by adding material.
Other advantages are the quick set-up times and the ability to produce very
complex assemblies as a single part.
The DMP Flex 350 production printer has a build platform of 275 x 275 x
420mm (including build plate) which can produce large size and high quality
parts in a variety of metals. The machine features easy cleaning and rapid
material switching.
DMP Factory 350
The system is upgradeable to the DMP Factory 350 solution , where an additional module, i.e. the Powder Management
Module (PMU) provides the customer with increased powder management and a closed powder handling system. Use the
instructions and information in this guide to operate the DMP Flex 350 production printer. Before operating this equipment,
please read this guide carefully to ensure safety.
1.1 Limitations of Warranty and Liability
This information is provided by 3D Systems for the convenience of its customers. It is believed to be reliable, but no
representations, guarantees or warranties of any kind are made as to its accuracy, fi tness for a particular use, or the results to
be obtained therefrom. The information is based in whole or in large part on laboratory work and does not necessarily indicate
performance in all conditions. Not withstanding any information provided by 3D Systems or its affi liates, the customer remains
fully responsible for determining which federal, state, or local laws or regulations, or industry practices are relevant to activities
in which it engages, as well as assuring that those laws, regulations, or standards are complied with under actual operating
conditions, and 3D Systems undertakes no responsibility in these areas. In no event is 3D Systems responsible for damages
of any nature, including special or consequential damages, resulting from the use of or reliance upon this information.
The customer assumes all risk resulting from the use of this information. Customers use of the materials that follow is an
acknowledgment of its agreement to the foregoing. Any customer not wishing to be bound should return this material to 3D
Systems. Nothing contained herein is to be considered as permission, recommendation, nor as an inducement to practice any
patented invention without permission of the patent owner.
1.2 Intended Use
The 3D Systems Direct Metal Printer (DMP) line is designed for the manufacturing of high precision metal parts using 3D
systems approved powders. The printed part properties mentioned in the 3D systems materials datasheet are guaranteed for
selected parts when the build files are generated using 3D Systems software, 3D Systems certified powders are used with the
corresponding parameters and the instructions as provided by 3D Systems are followed to their full extent where applicable.
Modification of the printer in any manner other than prescribed by 3D Systems or by any technician other than a 3D Systems
certified service engineer can negatively affect print quality and machine safety, and will result in a voided warranty.
1.2.1 Inert Gas Requirement
The printer, its print processes, and the materials intended for use with the printer are designed for operation with a chamber
of argon gas as the inert gas. Argon is a true inert gas that does not react with any metal material during printing, thus
providing a safe and stable processing environment. All certifications, material datasheets, process parameters, etc. for all
materials are developed with argon as the inert gas.
Any use of an inert gas other than argon, such as nitrogen for example, is at the user’s own risk, and 3D Systems shall not be
responsible in any way for the performance, safety, or part quality when a printer is used with an inert gas other than argon. If
an inert gas other than argon is used, it is the user’s responsibility to ensure the combination of metal material and inert gas is
safe because some materials, for example titanium or aluminum, are reactive with some inert gases, such as nitrogen.
